Summary Author: Edd Warddash

Spot the unconformities? This view is looking south across Loch Assynt, Scotland. The basement, adjacent to the loch is Lewisian Gneiss (some of the oldest rocks in Britain). Unconformably overlying this are the near horizontally bedded terrestrial sediments of the Neoproterozoic Torridon Group. Perhaps not as obvious but still recognizable is the unconformity visible to the left of the picture separating the Torridon Group from the marine sediments of the Eriboll Group, Cambrian (apparent dip of about 15-20 degrees to the left in the picture).
